Late March can feel like the moment crypto tax prep goes from “I’ll get to it” to “I need this done.” The good news: you don’t have to solve every tax question today to make real progress. What you can do this week is pull clean records, label what happened, and reduce the chance of double-counting—so that when you do file (or hand things to a pro), the hard part is already behind you.
The ‘minimum viable’ crypto records to pull this week
Think of this as your crypto tax documents checklist for late March: a simple packet that covers most situations without getting stuck in the weeds. If you used multiple apps, wallets, or chains, the goal is to create one organized folder per platform.
- Exchange exports: Download transaction history (trades, buys, sells), deposits/withdrawals, and any available gain/loss or “tax” reports. If the platform offers multiple export types (CSV vs. PDF), grab both.
- Wallet activity: For self-custody wallets, save transaction IDs/hashes for key moves (especially deposits/withdrawals tied to exchanges). If you use more than one wallet, list each wallet address (public address only) and which app it belongs to.
- Rewards/earn summaries: Collect staking, interest, airdrop, referral, or mining summaries if available. If the platform doesn’t summarize, export the raw transactions and note “rewards” in your own log.
- Transfer notes: Create a quick spreadsheet with: date, asset, amount, “from,” “to,” and a short label like “moved to cold wallet” or “sent to exchange to trade.”
- Account status notes: If an exchange account is closed or you lost access, write down what you remember (approximate dates, assets held, emails used). This helps later if you’re dealing with missing crypto records tax season problems.
Time-saver: name files consistently (e.g., “ExchangeName_TransactionHistory_2025-01-01_to_2025-12-31.csv”) so you can find them next year.
How to reconcile transfers so you don’t double-count activity
One of the most common late-March headaches is seeing the same movement show up twice: once as a withdrawal from one place, and again as a deposit into another. Good crypto transaction reconciliation is less about perfection and more about clear labeling.
- Separate “transfers” from “activity”: Mark wallet-to-wallet and wallet-to-exchange moves as transfers in your notes, so they don’t look like sales by accident.
- Match pairs: For each withdrawal, look for the corresponding deposit. Keep the transaction ID and both timestamps together in one line item.
- Watch timestamps and time zones: Different platforms may display times differently. If a withdrawal is late at night and the deposit is “next day,” it may still be the same transfer.
- Deduplicate repeated imports: If you imported data more than once into software or a spreadsheet, scan for identical transaction IDs or identical date/amount pairs.
- Flag the “unknowns”: If you can’t match something quickly, don’t guess. Add a “needs review” tag and move on—this keeps your momentum.
Common situations to document (without trying to decide tax treatment on your own): missing cost basis for older coins, tokens moved during a migration or rebrand, assets bridged across chains, or coins moved through a temporary address you no longer recognize. Your job this week is to capture the story and the paper trail.
When to stop DIY and call a qualified tax professional
If you’re doing late March crypto tax prep and you feel stuck, that’s often a sign you’ve reached the “organization is done; interpretation is next” line. A CPA or Enrolled Agent who is comfortable with digital assets can help you decide what documentation is sufficient and what needs deeper reconstruction.
Consider getting help if you have any of the following:
- Multiple exchanges and multiple self-custody wallets (especially across different chains)
- Significant “unknown” transactions, missing cost basis, or incomplete exports
- Closed accounts, lost login access, or limited history available
- Complex activity like bridging, token migrations, or frequent swaps
- Business use, payments, or anything that affects more than a simple investing picture
What to bring to a pro (an organized packet): your exports, your wallet address list, your “transfer notes” spreadsheet, any 1099 forms you received (if any), and a one-page timeline of major events (“started using Exchange A in May,” “moved to cold wallet in October,” etc.).
One more late-season reminder: be careful while downloading records. During tax season, scammers may impersonate exchanges or “tax support.” Use bookmarked URLs, enable multi-factor authentication, and treat unexpected messages as suspicious.
